First direct observation of carbon dioxide's increasing greenhouse effect
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley ...
New solar cell technology captures high-energy photons more efficiently
(Phys.org) —Getting the blues is rarely a desirable experience—unless you're a solar cell, that is.
Patented technique key to new solar power technology
(Phys.org)—A novel fabrication technique developed by UConn engineering professor Brian Willis could provide the breakthrough technology scientists have been looking for to vastly improve today's solar ...
8th century gamma ray burst irradiated the Earth, study finds
(Phys.org)—A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri ...
Dire outlook despite global warming 'pause': study
A global warming "pause" over the past decade may invalidate the harshest climate change predictions for the next 50 to 100 years, a study said Sunday—though levels remain in the danger zone.
Houston, we have another problem: Study shows space travel is harmful to the brain
(Phys.org)—As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation – which would bombard astronauts on deep space missio ...
Champion nano-rust for producing solar hydrogen
EPFL and Technion researchers have figured out the "champion" nanostructures able to produce hydrogen in the most environmentally friendly and cheap manner, by simply using daylight.
Cosmic radiation causes fluctuations in global temperatures, but doesn't cause climate change
Arctic ice melt sets stage for cold weather
(Phys.org) -- The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino effect ...
Is global warming causing harsher winters?
Millions of people in northern Europe are still battling snow and ice, wondering why they are being punished with bitter cold when—officially—spring has arrived and Earth is in the grip of global warming.
In tree rings, Japanese scientists find 8th-century mystery
In the late eighth century, Earth was hit by a mystery blast of cosmic rays, according to a Japanese study that found a relic of the powerful event in cedar trees.
An anomaly in satellite flybys confounds scientists
When space probes, such as Rosetta and Cassini, fly over certain planets and moons in order to gain momentum and travel long distances, their speed changes slightly for an unknown reason. A Spanish researcher ...
Solar radiation study offers clues on 20th century global warming wobbles
The amount of solar radiation passing through Earth's atmosphere and reaching the ground globally peaked in the 1930s, substantially decreased from the 1940s to the 1970s, and changed little after that, a ...
Study says Arctic melt season lengthening, ocean rapidly warming
The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in ...
